How many significant figures are in 20.8
6040 has 3 significant figures.
It is then 3650 to 3 significant figures
The rules for rounduing off numbers are as follows :- 1) If the first figure to be discarded is 5 or more, then the previous figure is increased by 1. Example : 5.1935 = 5.194 (4sf) = 5.19 (3sf) = 5.2 (2sf) = 5 (1sf) 2) Zeros must be kept to show the position of the decimal point or to indicate that zero is a significant figure. 1347 . . . when rounded to 3 significant figures then the 7 is discarded so 4 increases to 5. Thus, 1347 becomes 1350 (3sf). When rounded to 2 significant figures it becomes 1400 and to one significant figure 1000.
